From mboxrd@z Thu Jan 1 00:00:00 1970 From: akpm@linux-foundation.org Date: Tue, 04 Mar 2008 23:14:57 +0000 Subject: [patch 1/3] ia64: fix ptrace inside a namespace Message-Id: <200803042314.m24NEwT5002321@imap1.linux-foundation.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org From: Pavel Emelyanov The ia64 has its own sys_ptrace implementation and it was overlooked when the pid namespaces patches were sent. Use find_task_by_vpid() in it. Signed-off-by: Pavel Emelyanov Cc: "Eric W.
